ETG Claiming 666rwhp/601rwtq For F10 M5

There's the link. That's my comment on the page, reaching out to ask for dyno sheets and specifics. If this is true.......I'm speechless. Knew these cars had crazy power in them but this is insane. Hoping this is true. I know in the past it's been hard to contact them, although they did come through with dyno sheets of the old tune, and I'm hoping they do the same for this. I really, really want this to be true.

Just as a quick side note, I have been speaking with Jags from ETG today and he confirmed that these numbers are indeed from a tune only on a completely factory stock car. Unbelievable. To quote him, "0-150 mph is just insane"...I believe it. He mentioned that they have demo cars in CA and NC, so if there's anyone in either area who wants to see what this tune is like, that would I'm sure be some great evidence to have behind these numbers.

I have driven numerous M5's and M6's and I really cannot understand the results... the M6 is HEAVY, cumbersome, lumbers into and out of turns........ but it is kind of pretty... the M5 is a dolt with some nice smack down cornering abilities and a very nice feel.....

Feel and sense of speed usually are counter-intuitive though but I will take an M5 every day over the $20K more M6 beast

I also was obliterated today by a new 335is......... nice looking car and effing quick in a str8 line... very wowed

Was just reading some interesting points about this on another site. I think some of it is mental, but I really think its true. For me, the M5 at its weight and size is acceptable and does extremely well given these factors, and I love it for that. Plus, there's something sexy about four door super sedans that can out-accelerate supercars and outhandle sports cars. But the M6 is a two-door, and right away you expect way more from it. But it can't give you that. it's merely an M5 minus the doors and 150 lbs. Nothing new. All of a sudden performance that is amazing for a sedan seems a little disappointing for a 2 door sports coupe. Same reason I could never own a MB CL. Much sportier-looking, but nearly identical performance to the sedan it's based on. Can't do that. M5 for me.

I'd tend to agree but they do have dyno sheets for many of their tunes, all seeming very legitimate. Also, I've read some posts by happy customers occasionally on other forums, including the F10 M5. This seems impossible, but they seem amiable to having people come to drive the car. Trust me, if I was in SoCal or NC I'd have been over to either shop the second I got the email invitation to do so. I think it would be interesting to take one for a test drive and bring a comparison car.

On a dyno one can set up sub optimal conditions... then re-jig/retune and get a MASSIVE number at "optimal" conditions (in a workshop) but in the real world on a road, or wet race track or HUGE runway all that matters is how that mother effer under you performs with you in the saddle at that time...

I have seen high pwer tuned cars and V8 supercars do so well on a dyno or in a wind-tunnel only to see the same "perfect car" fail when a 50mph cross wind blew its light ASS chassis off the road...

Dynos are great for tuning in situ but get that car on the bitumen and see how it really deals

A horsepower claim without a dynograph or timeslip is just an unsubstantiated claim. Why do tuners do this? Well, the tuners on this network do not. They back up their claimed figures with real numbers. ECU Tuning Group on the other hand makes a lot of bold claims with little to no substance. An example? They call themselves the world's #1 ECU tuner. Seriously. What is that based on? Self-proclamation apparently. If ECU Tuning Group is the number one ECU tuner in the world then BimmerBoost is the world's number one BMW website. The latter is closer to being true than the former.

Here is the claim:

Now you would think the highest horsepower level ever achieved thus far on the F10 M5 would be big news. Notice the 0 facebook shares? Notice how nobody is talking about this? Well this site doesn't just let BS like this fly and people get taken advantage of.

How do you post such monumental tuning news without a dynograph? Without a picture? At least show an M5 with the post if you're trying to pull a fast one.

Choosing a realistic number to lie about is a good idea as well. The current F10 M5 and S63TU horsepower record is held by Switzer with a 604 wheel horsepower pull. That is with a piggyback tune, exhaust system, and filters. ECU Tuning Group is claiming 666 wheel horsepower tune only. So only about ~145 wheel horsepower over stock without supporting mods and exceeding the highest number achieved by 62 wheel horsepower tune only.

To note, ECU Tuning Group has never been referenced on this website in regards to a dyno or performance tuning record. On any platform. Ever. The only time they are mentioned (before Singh Autosport changed their name to ECU Tuning Group and then called themselves #1 ) is when they make ridiculous unsubstantiated claims. Back in 2010 they claimed to be the first to reprogram the E71 X6M in North America also without a dynograph as support and after other tuners had shown dyno results with their tunes on the X6M months in advance. They at least had the decency to show a picture of an X6M with a laptop sitting in it that time though.

This website does not doubt ECU Tuning Group has tunes available. They may even have some tuning skill and merit. But this claim is just ridiculous nonsense designed to suck unsuspecting people in to be taken advantage of and this network will not stand idly by and not point it out like the others.

As a professional courtesy, BimmerBoost will gladly drive out to ETG's location in Los Angeles and pay for a dyno run on a Dynojet for an M5 with this tune. If ETG backs up their 666 wheel claim BimmerBoost will post a retraction, pay for dinner at the restaurant of ETG's choice, and offer a year of free sponsorship.

Will ECU Tuning Group accept this offer? Nope. Because they can't back this up. If they really hit 666 wheel horsepower there would be a graph and this would be all over the place. And Jags (the owner) no, a funky manipulated European dynograph doesn't count. Additionally, if you are posting European dynographs what actual tuning are you doing at your location in Beverly Hills? It raises a large question if the only dynos you share are European dynos as if someone else's software is being purchased and then resold at markup. Another tuner did this and also marketed with MAHA graphs when they were sourcing from a European tuner. Keep in mind, that by no means implies the software is bad as it's likely quite good. Just not 666 wheel record breaking never been seen before and never will be seen again good.

So what's the truth here? You go ahead and decide but it's not hard to see what is really going on.

All good points. I really would like to see some kind of dyno numbers, if only to see what they have to offer. I've been wondering about them for a while now, and I had no idea about the N54 thing. I've only known about them for a couple years. @Sticky the scenario you outlined above is what I hope would happen, its not that I trust them blindly, and I sat by watching as people got ruined by ASR, Evosport, and others. I've seen the forum battles, and I've seen a lot of false accusations from people on many forums towards many tuners, some legit and some not. So, I guess after all that, I am skeptic of everything, but having seen many positive write-ups by various people (with different types of cars), I figure at the least they must have some kind of decent product. I'm not saying they shouldn't be put to the test, they should. Everyone should. If Dinan says they have a new tune I want to see dyno numbers. I guess I am just a little more optimistic than I should be, that's all. Given what you've gone through with your car, I can imagine being much more pragmatic about things, most definitely.

They don't really have anything man. I follow the tuning world closely, CLOSELY, and have seen nothing of merit.

All I've been through is a complex build. My car has set several records along the way. At no point did my tuner claim some absurd number that would be reached tune only or anything like that.

No but you have more experience in general than I do in dealing with tuners and whatnot. So of course your viewpoint is extremely relevant.

I mean look at this:

Is that someone who has the skill to do what nobody has ever done on a platform? I doubt it.

Not my position to judge. Do I think that was a good post by him? No. For me, dyno numbers are all that matters, same with you I'm sure. I don't care if the guy is selling coke out of the front office, if the tunes are legit then that's all I care about. Tell you what. If I can scrape together the funds to buy an F10 M5, I will let them tune it, and get it dyno'd before/after. Hell, I'd love to have everyone on here see that process all the way through. I'm coming at this from a neutral standpoint.

At the end of the day, after seeing all the sh*t being flung at tuners by other tuners. Don't get me wrong...i'm not pro-anybody. I don't have any loyalties. I remember reading some terrible things being posted about Gintani by certain members on certain boards back in the day. And then I found your site, and was blown away by what an amazing job they had done with your car. The ETG thread on MBW is primarily stocked with MHP fanboys ripping them apart, meanwhile a year after that happened MHP is banned and Andy is...well who knows. I've seen threads claiming Speedriven is a scam. Death threats from one shop owner to another...crazy things that at the time seem believable when substantiated by others but looking back are ridiculous. I guess my point is, I've seen and heard so much BS that at this point, I just want to see cars on dynos, and thats it. As do you, and everyone else on this site. That's why we're all here. And my offer above stands. If by the grace of god I can afford an F10 M5 in the near future, I will be the guinea pig for ETG's stage 2 tune so all of GermanBoost can see what is truly the case. If it's true, awesome. If its not, then we will all know. Tl;dr - I'm as skeptic as you are. I just want to give them a chance, everybody gets one with me. But only one.

The tuning world is definitely dirty but this site keeps the good ones here. We at least try to and weed out the crap throwing it out the door.

With this particular tuner, I've seen too much BS to believe this. I mean just based on the platform alone is the M5 getting 140+ rear wheel horsepower tune only with no supporting mods? I mean it's absurd to begin with.

FYI, sorry didn't mean to come across like that. I'm doing like 8 different things on my computer right now, and am typing as fast as I can think :p You seem to have only dealt with reputable guys, my point would have better been expressed as "You know from all your experience in making this site, and as a member of other sites, what tuners really are like. You are much more experienced in that than I am, and your opinion is highly relevant, and rightly so." No offense meant.

Mostly I agree. I just like to play devils advocate. And, I guess I'd like to hope that you can flash an S63 to 780+ hp. If I am in a position to put them to the test I will most definitely.

I've made mistakes. SSP the most glaring one. Speaking of which, I owe it to people to share my experience so they don't get burned by SSP like I did.

Live and learn I guess. At least now we know. Was going to say, hope that's coming along. Good thing the F10s haven't needed built DCT boxes because it seems that there's no reliable option for that so far. And I for one definitely appreciate hearing about it from someone who is doing it first hand.

Hmm that sounds about right. My m3 put down 700whp on the butt dyno when I switched to their high performance air freshener and tune. It was super easy I sent them $1000 and they flashed my car via satellite... At least that's what they told me
